In this tutorial, we’ll create an intermediate level Foliage Scatter tool using the Procedural Content Generation (PCG) Framework available in Unreal Engine 5.5.
We’ll utilize techniques to generate point clusters; ignore terrain normals; use subgraphs and combine them to create reusable PCG graphs and employ node debugging to develop PCG graphs.
